Minister for Agriculture and Biosecurity Damien O'Connor speaks with Kathryn Ryan about the cattle cull on 28 affected farms to put a halt to mycoplasma bovis disease. The Minister has acknowledged the failures in the national reporting system - NAIT - that is supposed to track animals from birth to slaughter, or live export. The disease outbreak is just one of a catalogue of major issues for MPI, including the discovery of the Bonamia Ostreae parasite in farmed oysters on Stewart Island, which has seen all farmed oyster beds on the island being pulled up - again in a bid to try to avoid the spread to wild oyster stocks.

RNZ Senior Manager, Carol Hirschfeld, has resigned over a meeting she had with the Broadcasting Minister Clare Curran last December. The meeting has already attracted political criticism from National, as it was not included in the minister's diary. The RNZ Chief Executive Paul Thompson says Ms Hirschfeld had repeatedly assured him that as Head of News, her meeting with Clare Curran last December was coincidental and that she and the Minister had talked after bumping into each other by chance in a Wellington cafe.  Mr Thompson says however, Ms Hirschfeld told him on Sunday the meeting had been pre-arranged. RNZ Political Editor Jane Patterson discusses the implications.
